| 4 | * cs4232.c |
| 5 | * |
| 6 | * The low level driver for Crystal CS4232 based cards. The CS4232 is |
| 7 | * a PnP compatible chip which contains a CS4231A codec, SB emulation, |
| 8 | * a MPU401 compatible MIDI port, joystick and synthesizer and IDE CD-ROM |
| 9 | * interfaces. This is just a temporary driver until full PnP support |
| 10 | * gets implemented. Just the WSS codec, FM synth and the MIDI ports are |
| 11 | * supported. Other interfaces are left uninitialized. |
| 12 | * |
| 13 | * ifdef ...WAVEFRONT... |
| 14 | * |
| 15 | * Support is provided for initializing the WaveFront synth |
| 16 | * interface as well, which is logical device #4. Note that if |
| 17 | * you have a Tropez+ card, you probably don't need to setup |
| 18 | * the CS4232-supported MIDI interface, since it corresponds to |
| 19 | * the internal 26-pin header that's hard to access. Using this |
| 20 | * requires an additional IRQ, a resource none too plentiful in |
| 21 | * this environment. Just don't set module parameters mpuio and |
| 22 | * mpuirq, and the MIDI port will be left uninitialized. You can |
| 23 | * still use the ICS2115 hosted MIDI interface which corresponds |
| 24 | * to the 9-pin D connector on the back of the card. |
| 25 | * |
| 26 | * endif ...WAVEFRONT... |
| 27 | * |
| 28 | * Supported chips are: |
| 29 | * CS4232 |
| 30 | * CS4236 |
| 31 | * CS4236B |
| 32 | * |
| 33 | * Note: You will need a PnP config setup to initialise some CS4232 boards |
| 34 | * anyway. |
| 35 | * |
| 36 | * Changes |
| 37 | * John Rood Added Bose Sound System Support. |
| 38 | * Toshio Spoor |
| 39 | * Alan Cox Modularisation, Basic cleanups. |
| 40 | * Paul Barton-Davis Separated MPU configuration, added |
| 41 | * Tropez+ (WaveFront) support |
| 42 | * Christoph Hellwig Adapted to module_init/module_exit, |
| 43 | * simple cleanups |
| 44 | * Arnaldo C. de Melo got rid of attach_uart401 |
| 45 | * Bartlomiej Zolnierkiewicz |
| 46 | * Added some __init/__initdata/__exit |
| 47 | * Marcus Meissner Added ISA PnP support. |
